Writing BDD Test Scenarios with Chat GPT

Behavior Driven Development (BDD) is a branch of Test Driven Development (TDD). BDD uses human-readable descriptions of software user requirements as the basis for software tests.

Here’s an example of a Behavior Driven Development (BDD) scenario for an e-commerce application using the Gherkin syntax;

Gherkin is a business-readable, domain-specific language used for describing the behavior of software systems in a structured format. It is primarily used in Behavior Driven Development (BDD) to write scenarios and acceptance criteria in a human-readable manner.

Gherkin uses a set of keywords to define the structure and components of a scenario. The main keywords include:

Feature: Represents a high-level feature or functionality of the system.

Scenario: Describes a specific test scenario or use case.

Given, When, Then: These keywords are used to describe the steps of the scenario.

Given: Represents the initial state or preconditions of the scenario.

When: Represents the specific action or event being performed.

Then: Represents the expected outcome or result of the action.

Gherkin scenarios are written using a Given-When-Then structure to ensure clear communication and understanding between stakeholders, developers, and testers. It promotes collaboration and shared understanding of the desired system behavior.

Gherkin scenarios are written in a structured format using plain text, making them easy to read and understand. They provide a shared language that can be used by all stakeholders, including business analysts, developers, and testers, to communicate and collaborate on the desired system behavior and It can be executed using various BDD frameworks, which parse the Gherkin syntax and automate the execution of the scenarios as tests, helping to ensure that the system behaves as expected.

    And I have a product with the name "iPhone 12"
    When I navigate to the product page of "iPhone 12"

In the example above, we have scenarios covering different aspects of managing a shopping cart in an e-commerce application, such as adding products, removing products, updating quantities, applying discounts, and proceeding with checkout. Then each scenario follows the given structure to define the starting context.
